Heide, your Kozulas are beautiful.
When Kozula made her crosses she was a member and a moderator of one of the Polish gardening forums. In November 2009 she had sent all her seeds to one of the forum members, to send the seeds to people who wanted to grow her tomatoes and select them. From this moment seeds were exchanged during forum swaps and nobody organized or coordinated the process of selection. Until now, those seeds are circulating between gardening forums members, some of them are sold by Polish and foreign online shops. After years some of those varieties disapeared, some of them do not have one "propper" version. There may be problems with accidental crossings too. But I love Kozulas, this year I had K/10, K/113 and no-K/141 (pink beefsteak, instead of red-yellow zebra).
Two years ago some of my forum members looked for seeds with low F numbers and started selection from the beginning.
Here is a link to Kozula's post containg first list of her crosses and her information about parent varieties. Numbers 1-11 she gave tomato varieties, they are not her crosses. Kozula's crosses start from number 12.
